TRANSOM-LIFTER.

SPECIFICATION forming part Of Letters Patent NO. 639,139, dated December12, 1899.

Application filed July 6, 1899. Serial No. 722,946. (No model.) I

To (tZZ whont it may concern:

Be it known that I, GEORGE BICKELHAUPT, of the city of New York, boroughof Manhattan, in the county and State of New York, have invented a newand Improved Operating Mechanism for Sashes, Scuttles, Skylights, c. ofwhich the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved operatingmechanism for sashes, scuttles, skylights, and like devices, and whichis simple and durable in construction and arranged to securely lock theskylight, sashes,or like devices in place and to permit the operator toquickly and conveniently swing the same to open position for instantescape of persons in case the building is on fire or for ventilation orother purposes.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

A practical embodiment of my invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a sectional side elevation of the improvement as applied toa scuttle, shown in a closed position. Fig. 2 is an enlarged sectionalside elevation of part of the improvement and with the parts in positionfor swinging the scuttle open. Fig. 3 is a transverse section of thesame on the line 3 3 in Fig. 2, and Fig. 4 is a similar view of the sameon the line i 4: in Fig. 2.

The improved operating mechanism illustrated in the drawings is shownapplied to a scuttle A, hinged at B to a scuttle-frame 0, attached inthe usual manner to the roof of a building. On the under side of thescuttle A, preferably at one o at both sides and within the opening ofthe frame 0, is secured a guideway D, extending longitudinally andpreferably made of a square tube having a slot D in the bottom,transversely-extending teeth or notches D being formed inlflangesdepending from said bottom at opposite sides of the slot D, as will bereadily understood by reference to Figs. 1, 2, and 3.

In the guideway D is mounted to travel one or more friction-rollers E,journaled on the forward end of a lever F, fulcrumed at or near itsmiddle, at F, on one side of the frame C, so that when a swinging motionis given to the lever F in the direction of the arrow 0. thefriction-rollers E cause an upward swinging of the scuttle A into anopen position, as shown in dotted lines in Fig. 1. On the forward end ofthe lever F is mounted to slide a catch G, having longitudinal slots G,through which extend transverse bolts H, carried by said lever F, tosupport the catch and to limit its forward and backward sliding motionon the lever. The catch Gis held in a forward position by a spring I,coiled on a rod 1, secured to a lug F projecting from the bottom of thelever F, and the free end of the rod I extends loosely through ashoulderG projecting from the catch G. The spring I rests with one end on thelug F the other end resting on the shoulder so that when the catch isslid rearward the springI is compressed, and when the catch is releasedthe spring I forces the catch back into a forward position, as shown inFig. 1.

The extreme outer end of the catch G is formed with a nose G adapted toengage a keeper J, secured to the inside of the frame C, so that whenthe nose engages the said keeper, as illustrated in Fig. 1, then thescuttle A is locked against opening, as the catch G is held on the leverF and the latter by the friction-rollers E in engagement with theguideway D, secured to the under side of the scuttle.

Now in order to release or.withdraw the catch G from the keeper J and toimpart an upward swinging motion to the scuttle A, I provide a rope K,secured to the rear end of the catch G and extending along the underside of the lever F to and around a pulley L, journaled at the rear endof said lever. The rope K then extends forward to pass over a pulley N,journaled in the frame .I, as shown in Fig. 1, the rope then extendingdownward to be attached to a cleat and to be within convenient reach ofthe operator when it is desired to open the scuttle for ventilating,escaping, or other purposes. By reference to Fig. 1 it will be seen thatwhen a pull is exerted on the rope K in the direction of the arrow 5,then the rope K imparts a rearward sliding motion to the catch G againstthe ten- Patentsion of the spring I, the nose G moving out of engagementwith the keeper J. hen the catch G reaches its rearward sliding limit bythe forward Walls of the slots G abutting against the bolts H, then afurther pull is exerted on the rope K in the direction of the arrowb,which causes a swinging of the lever 'F in the direction of the arrowat, so that the friction-rollers E, traveling in the guideway D, causeanupward swinging of the scuttle A, as indicated in dotted lines inFig. 1. As soon as the scuttle has been swung open the desired distancethe operator releases the rope K, so that the spring I forces the catchGforward to engage the nose G with the corresponding tooth D on thebottom of the guideway D, and thereby lock the lever and guide- Way,together with the scuttle A, in position, as will be readily understoodby reference to Fig. 1. When it is desired to again close the scuttle A,the operator pulls on the rope K to first withdraw thecatch G from thetooth D and then upon gradually releasing the rope the scuttle is causedto swing downward owing to its weight, the catch remaining in awithdrawn position until the scuttle has finally closed on the frame 0.iVhen the operator now fully releases the rope K, the catch Gshootsforward to again engage with its nose G the keeper J' to lock thescuttle A in position against opening from the outside without anyfurther fastening devices.

The device is very simple and durable in construction, is not liable toget out of order, and serves to securely lock the skylight, scuttle,sashes, or like device in a closed position and allows of swinging thedevice into an open position and looking it therein until it is againdesired to close it, as above explained.

Having thus fully described my invention, I claim as new and desire tosecure by Letters 1. An operating mechanism for sashes,scuttles,skylights and like devices, comprising a guideway on the device to beopened or closed, a lever having a sliding connection at one end withsaid guideway, so that when a swinging motion is given to the lever acorresponding movement is given to the device to be opened or closed, acatch carried by the lever and a dapted to engage the guideway of thedevice, or the frame thereof, to lock the device opened or closed, andflexible means under the control of the operator, for operat ing thecatch and imparting a swinging motion to said lever in one directiononly, the return movement of the lever being accomplished upon a partialrelease of the flexible connection by the weight of the actuatingdevice, substantially as shown and described.

2. An operating mechanism for sashes,scuttles, skylights and likedevices, comprising a guideway on the device to be opened or closed,

a lever having friction-rollers mounted to.

travel in said guideway, a slidingand spring pressed catch on said leverfor engaging the guideway of the device to lock the device open, or theframe thereof, to lock the device closed, and a flexible means under thecontrol of the operator and connected with said lever and catch, toallow of withdrawing the catch and imparting a swinging motion to saidlever, substantially as shown and described.

3. An operating mechanism for sashes,scuttles, skylights and likedevices, comprising a guideway on the device to be opened or closed, alever having friction-rollers mounted to travel in said guideway, acatch on said lever, a flexible means under the control of the operatorand connected with said lever and catch, to allow of withdrawing thecatch and imparting a swinging motion to said lever, and teeth on theunder side of said guideway and adapted to be engaged by said catch,substantially as shown and described.

4. An operating mechanism forsashes,scuttles, skylights and likedevices, comprising a guideway on the device to be opened or closed, alever having friction-rollers mounted to travel in said guideway, acatch on said lever, a flexible means under the control of the operatorand connected with said lever and catch, to allow of withdrawing thecatch and imparting a swinging motion to said lever, and a fixed keeperadapted to be engaged by said catch when the device is in a closedposition, substantially as shown and described.

5. An operating mechanism for sashes,scuttles, skylights and likedevices, comprising a guideway made tubular and having a slot in thebottom and transverse teeth on said bottom, a lever extending with itsfree end into said slot and having at its free end frictionrollersengaging said guideway, a springpressed catch mounted to slide on thefree end of said lever, and a rope connected with said catch andextending over a pulley on the rear end of the lever and over fixedguideways, to be under the control of the operator, substantially asdescribed.
